But for Valentine’s yesterday, the Netflix show’s official Twitter released the technology from episode ‘Hang the DJ’, with a website called coach.dating, allowing fans a future glimpse at when their relationship will ‘expire’.

In the show, the dystopian “99.8% accurate” app pairs besotted Frank and Amy together for 5 years, after countless short Tinder-style hookups.

A couple must decide together to view their “expiry date”, but when Frank cheats the system, their relationship is slashed to just one day.

User @MillyDunne’s partner Matt cheated the app, cutting their relationship from nine years to three minutes.

Black Mirror brazenly replied , informing them “the system will be assessing your reaction to the painful premature termination of a treasured relationship and will adjust and improve its profile of your eventual chosen one accordingly”.

Others dismissed the show’s judgements outright, with Kamryn Pack tweeting: “Hey @blackmirror I had to fix me and @CassadyRainbow ‘s timer”, with a picture of 11 year score scribbled out, replaced by ‘Forever’.

A few lovebirds came out unscathed, with Brad Warzala excitedly revealing to followers he’d found his ‘ultimate match’, to which Black Mirror replied: “Congratulations, Brad on your ultimate match. Your pairing day is tomorrow.”

As news spread, dozens of others enjoyed interacting with the show’s official Twitter which kept replying back.
